I've been trying to build some circuits that use logic gates, without using pre-made chips. My main goal is to further my understanding of the subject, but it'd be nice to make something useful in the process.
After a lot of failed attempts and googling I landed on this question, which works great. But I feel that the current consumption will be very high (since the inverters will basically send a load of current to ground when they're low?). This is especially true if you want to use many gates.
It seems to me that you need to 'black box' the logic gates so that you can chain them as much as you like without much worry. The inverters do this, but at the cost of current. Is there a better way? Is learning the hard physics behind it all the only way to really make complex logic circuits, so I'm just moving out of my depth? I have a strong understanding of the gates themselves, and designed my circuits as pure gates already, but the actual physical implementation is very different.
So my question would be:
Is there a simple and effective way of blackboxing RTL logic gates so that they can be chained?
Edit: I just recalled that NOR can be used to construct other gates – so I suppose the solution would be a design for a NOR gate that can be treated as modular.
